c functions usage on D3

[philippe GRACIA]

can someone help use on using C socket functions on D3 10.3 ?

we're trying to set timeout on incoming connections using %setsockopt without success ...

thanks for your help !

Could you post some sample code and the OS you're using?

hello!

D3 linux 10.3.4 on redhat 8.4

very simple code ( from the doc, but setsockopt is very poorly documented !)

 'test.socket' size = 1086                                  
      cfunction socket.builtin                              
      include dm,bp,includes sysid.inc                      
      include dm,bp,unix.h socket.h                        
* Create a socket                                          
      listen.port=4062                                      
      buffer.size=1024                                      
      timeout=255                                                                                                    
      fd=%socket(af$inet, sock$stream, 0)                  
******* <- here !                                          
      ret=%setsockopt(fd,SOL$SOCKET,SO$RCVTIMEO, timeout,1)
      print ret                                            
* Bind the socket to a local Ethernet port.                
* Use default address.                                      
      char buffer[buffer.size]                              
      if %bind(fd, af$inet, inaddr$any, listen.port)<0 then
         crt "bind failed"; stop                            
      end                                                  
* Wait for incoming connection and allow up to              
* three more to be waiting.                                
      %listen(fd, 3)                                        
*      debug                                                
* Accept a connection until got them all                    
      loop                                                  
      address=0; port=0                                    
      socket=%accept(fd, &address, &port)           
      until socket<0 do                                    
      crt "Called by address ":address:", port #":port      
* Read data from the data link                              
      %recv(socket, buffer, buffer.size)                    
* Done with this connection, close it                      
      print trim(buffer)                                    

      char buffer[buffer.size] ; * re-init                  
      %closesocket(socket)                                  
      repeat
